Kotzebue, Alaska

Kotzebue or Qikiqtaġruk is a city in the Northwest Arctic Borough in the U. S. state of Alaska. It is the borough's seat, by far its largest community and the economic and transportation hub of the subregion of Alaska encompassing the borough; the population of the city was 3,201 as of the 2010 census, up from 3,082 in 2000. The city has an All-America City award Owing to its location and relative size, Kotzebue served as a trading and gathering center for the various communities in the region; the Noatak and Kobuk Rivers drain into the Kotzebue Sound near Kotzebue to form a center for transportation to points inland. In addition to people from interior villages, inhabitants of the Russian Far East came to trade at Kotzebue. Furs, seal-oil, rifles and seal skins were some of the items traded. People gathered for competitions like the current World Eskimo Indian Olympics. With the arrival of the whalers, gold seekers, missionaries the trading center expanded. Kotzebue is known as Qikiqtaġruk, which means "small island" in Iñupiatun, the language spoken by Iñupiat.

In the words of the late Iñupiaq elder Blanche Qapuk Lincoln of Kotzebue: "Iḷiḷgaaŋukapta tamarra pamna imiqaqtuq. Taavaasii kuuqahuni taiñña Adams-kutlu Ipaalook-kutlu, taapkuak piagun tavra. Taiñña suli Katyauratkutlu, Lena Norton tupqata piagun tavra kuuk suli taugani... Manna uvva qikiqtaq, Qikiqtaġruŋmik tavra atiqautiginiġaa qikiqtaupluni. Nunałhaiñġuqtuq marra pakma.". Kotzebue gets its name from the Kotzebue Sound, named after Otto von Kotzebue, a Baltic German who explored the sound while searching for the Northwest Passage in the service of Russia in 1818. A United States post office was established in 1899. In 1997, three 66-kw wind turbines were installed in Kotzebue, creating the northernmost wind farm in the United States. Today, the wind farm consists of 19 turbines, including two 900 kW EWT turbines; the total installed capacity has reached 3-MW, displacing 250,000 gallons of diesel fuel every year. On September 2, 2015, U. S. President Barack Obama gave a speech on Climate Change, in Kotzebue, becoming the first sitting president to visit a site north of the Arctic Circle.

Kotzebue lies on a gravel spit at the end of the Baldwin Peninsula in the Kotzebue Sound. It is located at 66°53′50″N 162°35′8″W 30 miles from Noatak and other nearby smaller communities, it is 33 miles north of the Arctic Circle on Alaska's western coast. According to the United States Census Bureau, the city has a total area of 28.7 square miles, of which 27.0 square miles is land, 1.6 square miles, or 5.76%, is water. Kotzebue is home to the NANA Regional Corporation, one of thirteen Alaska Native Regional Corporations created under the Alaska Native Claims Settlement Act of 1971 in settlement of Alaska Native land claims. Kotzebue is a gateway to Kobuk Valley National Park and other natural attractions of northern Alaska. A Northwest Arctic Heritage Center is located in the town to acclimate National Park Service travelers. Nearby Selawik National Wildlife Refuge maintains office space in the town. Kotzebue has a dry subarctic climate bordering on the Tundra climate, with long, somewhat snowy, cold winters, short, mild summers.

Electromagnetic wave equation

The electromagnetic wave equation is a second-order partial differential equation that describes the propagation of electromagnetic waves through a medium or in a vacuum. It is a three-dimensional form of the wave equation; the homogeneous form of the equation, written in terms of either the electric field E or the magnetic field B, takes the form: E = 0 B = 0 where v p h = 1 μ ε is the speed of light in a medium with permeability μ, permittivity ε, ∇2 is the Laplace operator. In a vacuum, vph = c0 = 299,792,458 meters per a fundamental physical constant; the electromagnetic wave equation derives from Maxwell's equations. In most older literature, B is called magnetic induction. In his 1865 paper titled A Dynamical Theory of the Electromagnetic Field, Maxwell utilized the correction to Ampère's circuital law that he had made in part III of his 1861 paper On Physical Lines of Force. In Part VI of his 1864 paper titled Electromagnetic Theory of Light, Maxwell combined displacement current with some of the other equations of electromagnetism and he obtained a wave equation with a speed equal to the speed of light.

He commented: The agreement of the results seems to show that light and magnetism are affections of the same substance, that light is an electromagnetic disturbance propagated through the field according to electromagnetic laws. Maxwell's derivation of the electromagnetic wave equation has been replaced in modern physics education by a much less cumbersome method involving combining the corrected version of Ampère's circuital law with Faraday's law of induction. To obtain the electromagnetic wave equation in a vacuum using the modern method, we begin with the modern'Heaviside' form of Maxwell's equations. In a vacuum- and charge-free space, these equations are: ∇ ⋅ E = 0 ∇ × E = − ∂ B ∂ t ∇ ⋅ B = 0 ∇ × B = μ 0 ε 0 ∂ E ∂ t These are the general Maxwell's equations specialized to the case with charge and current both set to zero. Taking the curl of the curl equations gives: ∇ × = ∇ × = − ∂ ∂ t = − μ 0 ε 0 ∂ 2 E ∂ t 2 ∇ × = ∇ × = μ 0 ε 0 ∂ ∂ t = − μ 0 ε 0 ∂ 2 B ∂

Music of Epirus (Greece)

The music of Epirus, in Epirus, northwestern Greece, present to varying degree in the rest of Greece and the islands, contains folk songs that are pentatonic and polyphonic, characterized as relaxed and exceptionally beautiful, sung by both male and female singers. Distinctive songs include shepherd's songs and drinking songs; the clarinet is the most prominent folk instrument in Epirus, used to accompany dances slow and heavy, like the menousis, podhia, sta dio, sta tria, kentimeni, koftos and tsamikos. The polyphonic song of Epirus constitutes one of the most interesting musical forms, not only for the east Mediterranean and the Balkans, but for the worldwide repertoire of the folk polyphony like the yodeling of Switzerland. Except from its scale, what pleads for the old origin of the kind is its vocal, collective and modal character; the corresponding dances are stately. Women's dances are noble, allowing for a minimum of leg and arm movement, calling for formal traditional attire: ankle-length black coats, gold thread tuques with a single long tassel, hammered gold jewellery.

USS Wanderer (SP-2440)

The second USS Wanderer was a patrol vessel that served in the United States Navy from 1917 to 1918. Wanderer was a motorboat built in 1913 at Norfolk, Virginia, by Craig Brothers, owned by R. F. Barret of Norfolk, she was acquired by the U. S. Navy for service as a section patrol boat during World War I. Inspected at the 5th Naval District on 13 April 1917 and designated SP-2440, she was placed in commission on the same day as USS Wanderer. Wanderer operated on local and section patrol duties for the duration of World War I, she was returned to her owner on 30 December 1918. Wanderer was one of two U. S. Navy ships named USS Wanderer in service during World War I, the other being USS Wanderer; this article incorporates text from the public domain Dictionary of American Naval Fighting Ships.
